Gridwave Puzzle: Complete — Privacy Policy
Last updated: 6 November 2026
HTR Games operates Gridwave Puzzle: Complete ("Gridwave", "the game").
For privacy questions and requests, contact htrwork@gmail.com.
1. The game and data stored on your device
Gridwave is a paid puzzle game with no in-game advertising or in-app purchases. You do not need to create an account or provide your name, phone number or email address to play.
The game can be played offline.
The game stores progress, stars, hints, cosmetics, language and audio settings, your statistics-sharing preference, and gameplay statistics on your device.
2. Your statistics-sharing choice
Statistics sharing is enabled by default. You can change this using the "Send statistics" checkbox in Settings → Privacy Policy. Your choice is saved between sessions.
Your choice does not restrict gameplay, progression, hints, rewards or other game features. Local progress and gameplay statistics continue to be saved when sharing is disabled.
When you turn statistics sharing off:
Before earning your first star: the game sends no gameplay statistics and no installation identifier. Earning stars afterwards while sharing remains disabled does not start any uploads.
After earning one or more stars: the game captures one final cumulative update at the moment you switch sharing off, marked as disabled. This replaces any update still waiting in the sending queue. The final update contains your installation identifier and gameplay statistics recorded up to that moment.
The final update does not wait for another star to be earned. It does not include moves, stars, hints, playing time or other gameplay data generated after you switched sharing off.
For example, if you disable sharing at 10 stars and later earn an 11th star while sharing remains disabled, the final update will not include that 11th star or the subsequent gameplay.
The final update can be sent once it has been saved locally and a connection is available. This also applies if earlier updates could not be delivered because you were offline.
If delivery fails, the game may retry the same unchanged final update when it runs with an available connection until delivery is confirmed. Retries do not add newer gameplay data. After delivery is confirmed, no further statistics updates are sent unless you turn sharing on again.
If you enable sharing again, later updates can include cumulative gameplay history, including history recorded locally while sharing was disabled.
Turning sharing off does not delete statistics already received by our server. See section 9 for deletion requests.
3. Gameplay statistics sent to us
The game generates a random installation identifier and stores it with the local save data.
This is not your Android advertising ID, a hardware identifier or a Google account ID. It allows our service to match updates from the same saved installation.
The same identifier is displayed as "User ID" at the very bottom of the scrollable in-game Privacy Policy.
Because updates can be linked through this identifier, these statistics are pseudonymous rather than fully anonymous.
While statistics sharing is enabled, a cumulative update is normally queued when you earn a new star. A queued update may be sent later when the game runs and an internet connection is available. The final update when sharing is disabled follows the rules in section 2.
An update can include:
The random installation identifier, app version, statistics revision, progress revision information and level catalog version.
Started, completed and starred levels; moves, attempts, wins, restarts, hints used or viewed, and active playing time.
Summaries of the first attempt, first win, first star and current attempt.
The first accepted move's cell and redirector orientations, whether the move came from the player or a hint, and comparison with the authored first move.
Indicators of whether the recorded gameplay history is complete and whether statistics sharing is enabled.
These are cumulative gameplay summaries. They do not include screen recordings or a complete timestamped stream of every action.
The game's statistics payload does not contain your name, contact details, advertising ID, precise location, contacts, photos, microphone recordings or payment card details.
4. Why we use this information
We use gameplay statistics to understand player progress and level difficulty, evaluate hints and puzzle balance, and identify problems with the game.
We do not use these statistics for personalised in-game advertising, and we do not sell personal information.
If you email us, we process your email address and the information you provide to respond to your enquiry or privacy request.
5. Hosting, service providers and Google Play
Statistics are sent over HTTPS to our statistics service hosted using Cloudflare.
Cloudflare processes network information needed to deliver and protect requests, which can include your IP address and other connection metadata.
The game does not include an IP-address field in its statistics payload; this infrastructure processing is separate from that payload.
We use service providers to operate the service. Information may also be disclosed where legally required or necessary to protect the service and its users.
Cloudflare Privacy Policy:
https://www.cloudflare.com/privacypolicy/
Purchasing and downloading the game, and Google Play review interfaces, are handled by Google Play under Google's policies.
We do not receive your complete payment card details.
Google Privacy Policy:
https://policies.google.com/privacy
The game does not use Firebase Analytics or AdMob.
6. Retention and your requests
Local progress, settings and statistics remain on your device until you remove the game's local data, subject to operating-system backup and restoration features.
Removing local data or uninstalling the game does not itself delete statistics already received by our server.
We retain installation-linked statistics for as long as reasonably necessary for the game-analysis and maintenance purposes described in this policy, unless a different period is required by applicable law.
You can contact htrwork@gmail.com with privacy questions or requests to access or delete information.
Because gameplay statistics are linked to a random installation identifier rather than an account, name or email address, we cannot identify your gameplay statistics from your name or email address alone. Please include the User ID displayed at the bottom of the in-game Privacy Policy so we can locate the relevant records.
We handle requests in accordance with applicable law. Instructions for requesting deletion are provided in section 9.
7. Security and international processing
We use HTTPS to protect statistics in transit and restrict administrative access to the statistics service.
No method of transmission or storage is completely secure.
Our infrastructure providers may process information in countries other than the country where you live.
8. External links and policy updates
External social, store and other links are governed by the relevant services' privacy policies.
We may update this policy when the game or its services change. The date at the top identifies this version.
9. Data deletion requests
To request deletion of your Gridwave Puzzle: Complete gameplay statistics stored on our servers:
Open Settings → Privacy Policy in the game.
Scroll to the very bottom of the policy text to find your User ID. This is the installation identifier used in statistics updates.
Email htrwork@gmail.com with the subject "Gridwave Data Deletion", include that User ID, and request deletion of the associated gameplay statistics.
Please record your User ID before clearing the game's local data, as the identifier for that saved installation may no longer be available afterwards.
We will delete the server-side gameplay statistics associated with that identifier, except information we are legally required to retain.
Deleting server records does not change your statistics-sharing setting or cancel an update still queued on your device. To stop further sharing, turn off "Send statistics". If you have earned one or more stars, the unchanged final update described in section 2 may still be delivered afterwards, including after a period without an internet connection.
If a pending update arrives after your records have been deleted, it can create a server record again. Re-enabling statistics sharing can also result in new submissions.
Deleting server-side statistics does not erase your local game progress or settings. These remain on your device until you clear the app's data or uninstall it, subject to operating-system backup and restoration features.
